A hand-held adhesive tape sealer

Abstract

The invention provides a handheld box tape-sealing device which at least comprises a shell seat, a front serrated knife, a roller and a tape fixing shaft. The shell seat comprises a head and a cover, the front serrated knife is positioned at the front end of the head, the roller is mounted in an inner cavity of the head, the tape fixing shaft is positioned in an inner cavity of the cover, the head and the cover are hinged through two elastic device, each elastic device is composed of a pin shaft, a spring and two supporting rods, each pin shaft is fixed in a hinging hole formed in a joint of the head and the cover, one end of each supporting rod is connected with the corresponding pin shaft while the other end of the same is connected with the corresponding spring, each spring and the corresponding supporting rods form a triangular structure, each two corresponding supporting rods are fixedly connected with the head and the cover respectively, the upper surface of the cover is a cambered surface which is bent upward and is in arc transition with a side wall plate of the cover, and the head inclines inward by 30 degrees along the arc direction of the cover. The elastic devices are added on two sides of the inner cavity of a device body to change angle of the head to enable the roller to press and stick a tape on a side box more easily for sealing, so that fatigue degree of wrists and arms is reduced.

Description

Technical field [0001] The invention relates to a hand-held tape box sealing device, which belongs to the technical field of carton sealing devices. Background technique [0002] Tape carton sealer, also known as carton sealing machine, has three types: semi-automatic machine type, grip type and body grip type. It is mainly used for carton sealing and is widely used in express delivery and product packaging. The above three types of carton sealers have their own strengths. Although the semi-automatic machine type is highly efficient, it cannot work for cartons that exceed a certain specification or less than a certain specification. The original intention of the grip type is to make the operation more comfortable, but efficient It is not high and is particularly inconvenient for side sealing; the other is the grip type, which is smaller in size and suitable for carton sealing of various specifications, and the side sealing is more convenient than the grip type. [0003] The grip-t...

AI Technical Summary

Problems solved by technology

When sealing the box, it must be unsealed from the side of the carton (when unsealing, the roller of the machine head should press the tape on the carton to pull the tape), so the traditional body-grip carton sealer is used when unsealing. To make the wrist bend down to the maximum extent (the maximum angle of wrist bending downward is 60°, and the maximum angle of upward bending is 70°, refer to ("Industrial Design Ergonomics" Second Edition), and lift it up if necessary arm, the wrist and arm can be very tired if repeated

And now the width of the tape for packaging is about 45mm, the tape for large cartons may be wider, and the cover of the body-grip box sealer must be wider than the tape to make the tape rotate smoothly, so the palm must be widened to a large extent , a bit strangled

Although the upper cover itself has a certain curvature, it is far from fitting the palm of the hand, because simply adding a curvature to the cover and increasing the inclination angle of the upper cover will increase the upward angle of the wrist during operation, and will also give wrist discomfort
